Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an angle indicator indicating a reclining angle of a child seat or the like, and a child seat including the angle indicator.
[0002]
[Prior art]
As an angle indicator indicating a reclining angle of a child seat, the one shown in FIG. 10 is known (Japanese Patent Application Laid-Open No. 2000-13270).
[0003]
The indicator 160 includes a case 161, a pendulum 163 swingably supported on a support shaft 162 in the case 161, a pointer 164 integrated with the pendulum 163, and a display surface 165 facing the pointer 164. And a cover 166 that covers the case 161.
[0004]
The pendulum 163 includes a weight 167, and the weight 167 always points vertically downward.
[0005]
A green zone 168 is provided on the display surface 165 by printing, sticking two-color molding, or the like, and a notice that a child seat should be installed so that the hands 164 enter the green zone 168 is displayed in a place where the child seat is easy to see. It is written in. Although not shown, a red zone is provided adjacent to the green zone 168.
[0006]
When the reclining angle of the child seat is proper, the pointer 164 enters the green zone 168. When the pointer 164 enters the red zone, it is recognized that the reclining angle of the child seat is out of the proper range.
[0007]
[Problems to be solved by the invention]
In the above-described conventional angle indicator, the pendulum 163 may shake due to the vibration of the automobile and hit the inner surface of the case 161 to generate abnormal noise.
[0008]
An object of the present invention is to provide an angle indicator that does not generate such abnormal noise and a child seat provided with the angle indicator.
[0009]
[Means for Solving the Problems]
An angle indicator according to the present invention includes a movable piece that can be tilted, a casing that accommodates the movable piece in a tiltable manner, a stopper provided in the casing, the movable piece can contact, and a movable piece. An elastic body that urges against the stopper is provided, and a release piece that separates the elastic body from the movable piece and makes it tiltable.
[0010]
In such an angle indicator, since the movable piece is pressed against the stopper by the elastic body, it does not hit the inner surface of the casing even if it is subjected to vibration, and no abnormal noise is generated.
[0011]
When measuring the angle, the release piece is operated with a fingertip or the like to separate the elastic body from the movable piece, and the movable piece is set in a free state in which the movable piece can be tilted. Thus, the movable piece assumes a posture corresponding to the posture of the angle indicator, so that the angle of the angle indicator can be known.
[0012]
In the present invention, the casing is provided with a window hole, and the movable piece is installed so as to face the window hole when in the neutral position, and to retreat from the window hole by tilting. A colored portion is provided on the inner surface of the movable member so as to face the window hole, the movable piece in the neutral position is disposed between the colored portion and the window hole, and The surface facing the hole may have a different color from the colored portion.
[0013]
With this configuration, when the angle indicator is inclined at a predetermined angle or more, the movable piece retreats from the window when the movable piece is in the free state, and the colored portion on the inner surface of the casing is visually recognized through the window. Is done. Thereby, it is recognized that the angle indicator is inclined to a predetermined angle or more.
[0014]
On the other hand, when the angle indicator is not so inclined, the movable piece is interposed between the window and the colored portion, and the color of the movable piece is visually recognized through the window. Since the color of the movable piece is different from the color of the colored portion, it is recognized that the angle indicator is not so inclined.
[0015]
When the color of the colored portion is red, and the movable piece facing the window hole is green or blue, it is "impossible" when the red color can be seen through the window hole, similar to a traffic signal. That is, when a green or blue color is seen through the window, it is perceived that the color is acceptable, so that it is possible to easily identify at a glance whether or not the degree of the inclination of the angle indicator is acceptable. Become.
[0016]
In the present invention, the movable piece includes a vertical portion extending in the vertical direction, and a horizontal portion connected to the lower end of the vertical portion and extending in the horizontal direction, and the stopper has the movable piece in a neutral posture. Sometimes, the bottom of the horizontal portion is disposed below the horizontal portion so as to abut, and a weight portion is provided at an upper portion of the vertical portion, and the weight portion has a movable piece in a neutral position. It may be configured to sometimes face the window hole.
[0017]
In such a configuration, when the inclination of the angle indicator is within a predetermined range, the lateral portion overlaps the stopper, and the weight portion faces the window hole. When the tilt of the angle indicator exceeds a predetermined range, the movable piece tilts so that one end of the horizontal portion is separated from the stopper, and the weight portion retreats from the window. Therefore, whether the inclination of the angle indicator is within the predetermined range or beyond the predetermined range can be almost binaryly identified.
[0018]
The child seat of the present invention is provided with such an angle indicator, and does not generate abnormal noise from the child seat installed in the seat of the automobile. Also, it is possible to easily know whether or not the child seat is installed in the seat.
[0019]
